BACKGROUND

1. Field

The present disclosure relates generally to navigational or positionalinformation systems, and more particularly, to devices, systems andmethods for controlling and storing sensitive information on a globalpositioning system (GPS) device.

2. Description of the Related Art

GPS (Global Positioning System) devices are everywhere. These devicesprovide a user with such information as latitude and longitude, accuratetime, heading, velocity, etc. GPS devices are particularly useful inautomobiles and other vehicles. Many individuals have multiple GPSdevices if they own, for instance, two cars that both have the device.Conventionally, most devices will allow a user to store information suchas address points in the internal memory of the device. Some deviceswill allow you to store this information on removable memory, e.g.,memory cards, optical media, etc. In the latter case, this can beparticularly helpful because a list of addresses, for instance, will beuseful to be moved from GPS device (e.g., a first vehicle) to GPS device(e.g., a second vehicle).

However, GPS related information can be quite sensitive. For instance,most persons will store their home address in the device as well as theaddresses of other contacts. This is not the kind of information that aperson would want other unauthorized individuals to have access to.

In another example, many persons would desire to retain information onpast trips (e.g., routes) that the vehicle has made. Typically, a GPSdevice is capable of storing information (e.g., in internal memory or onremovable memory) regarding the time and location of the vehicle duringusage. This information could prove quite useful for someone who wantsto track the vehicles usage, for example, an employer wanting to seewhere a company car was driven during a particular day, or a parent wholoans their child the car and wants to see where the car was taken.Again, the challenge here is to store this information in a form thatcan only be accessed by designated parties (for example, by the employernot the employee, and by the parent and not the child).

Therefore, a need exists for techniques for controlling and storingsensitive information on a GPS device and only allowing access todesignated parties.

A locational information module 122 will be provided for determining alocation of the device 100 and/or user. The locational informationmodule 122 may include a receiver and antenna ANT employing conventionallocational information processing technology such as Global PositioningSatellite (GPS) Technology, Loran Technology, or any other availablelocational technology, to indicate the exact location, e.g., latitude,longitude and altitude, of the device 100. Exemplary GPS receivers andantennas are described in U.S. Pat. Nos. 5,654,718 and 6,775,612, thecontents of both of which are herein incorporated by reference. It is tobe appreciated that the latitude, longitude and altitude may be used tointeract with maps stored in memory or in the storage module 110 ofdevice 100 to determine the city, state or address of the location thedevice 100. Furthermore, the locational information module 122 maycalculate routes traveled, velocity of a vehicle including the device100, etc., or alternatively, may send the position coordinates to theprocessing module 120 at a predetermined sampling period where theprocessing module will perform the calculations.

Furthermore, the device 100 will include a date and time module 124. Thedate and time module 124 will use standard computer chip processingtechnology widely in use, or alternatively, input from locationalinformation module 122, e.g., a GPS receiver, to supply the date andtime. The date and time may be associated with routes traveled and maybe employed to determine velocity of the user of the device 100 whetherin a vehicle, on a bicycle or while walking.

The device 100 will also contain a display module 104 for displaying alocation of a user, a map, coordinates, waypoints, frequently accessedaddresses, etc. This display may be in any current form in the art,including Liquid Crystal Displays (LCD), Light emitting diode displays(LED), Cathode Ray Tube Displays (CRT) or any other type of displaycurrently existing or existing in the future. The display module 104 mayalso include an audio output device 116, e.g., a speaker, headphonejack, etc., allowing the user to also hear audio output from the device100, e.g., audibly producing directions to a desired location orpredetermined address.

The device 100 of the present disclosure will contain a user inputmodule 126 to either receive user instructions via text input by the wayof buttons 108, a standard keyboard interface coupled to the device, ora character recognition capture device which translates user text inputinto alphanumeric characters. Preferably, the character recognitiondevice is a touch screen which overlays the display module 104 and textis entered via a pen-like stylus. Such input devices are standard andcurrently available on many electronic devices including portabledigital assistants (PDAs) and cellular telephones. Optionally,microphone 114 may be further coupled to the input module 126 forcapturing any audio information spoken by the user and the input modulewill further include an analog-to-digital (A/D) converter for convertingthe spoken audio information into a digital format. Furthermore, theinput module may include a voice recognition processor that translatesthe digital human voice into alpha numeric characters for user input.The user will utilize the user input module 126 to enter various data,for example, a plurality of destination addresses, waypoints, etc.

The storage module 110 includes internal storage memory, e.g., randomaccess memory (RAM), or removable memory such as magnetic storagememory; optical storage memory, e.g., the various known types of CD andDVD media; solid-state storage memory, e.g., a CompactFlash card, aMemory Stick, SmartMedia card, MultiMediaCard (MMC), SD (Secure Digital)memory; or any other memory storage that exists currently or will existin the future. The storage module 110 will store various types ofinformation such as the inputted destination addresses, routes traveledby the user, the user's home address, etc.

The device 100 will also include an encryption module 128. Theencryption module 140 will use conventional code encryption algorithmscurrently in use or that will be in use in the future such assymmetric-key algorithms, e.g., DES, Triple-DES, Blowfish, RC2, RC4,RC5, etc, and asymmetric-key algorithms, e.g., Diffie-Hellman, RSA,ElGamal, etc. to encrypt the data information that comes into the userinput module 126 and/or that is stored in the storage module 110. In oneembodiment of the present disclosure, the encryption module 128 willalways encrypt the data information, but in other embodiments, the userwill select whether to encrypt the data or to leave the dataunencrypted.

Upon initialization of device 100, processing module 120 prompts theuser via display module 104 or speaker 116 to select a code string thatthe user wishes to use. The user selects an appropriate code string andenters the code string into the device 100 with input module 126 viabuttons 106, microphone 114 or touch screen. The input module 126 sendsthe code string to the processing module which in turn sends this stringto encryption module 128. The encryption module 128 then uses this codestring to encrypt (using standard encryption algorithms identifiedabove) all addresses and route points (or just the addresses and routepoints that the user designates) and store this information in thestorage module 110. When the GPS device 110 is inactive, all informationin the storage module 110 is encrypted. When the GPS device 100 isactive, the information in the storage module 110 is sent to theencryption module 128 which after receiving the user's code stringdecrypts the information, and then sends the information to theprocessing module where it can then be presented to the user on thedisplay module 104.

Also note that in another embodiment, the GPS device 100 can function sothat the information written to the storage module 110 can only beaccessed by a user by inputting the code string. In other words, if theuser or another party wants to view past route information on tripstaken, or a list of addresses stored, the user must supply the codestring to the encryption module 128 which will then use the processingmodule 120 to decrypt the information and present that information onthe display module 104 of the GPS device 100. This code string could beuser designated to be required each time information is requested, oralternatively, automatically every time the GPS device 100 is turned on.

In another embodiment of the present disclosure, the GPS device 100 willinclude a hardware interlock 118 to prevent the removal of the storagemodule 110. The interlock 118 may be a detent configured to engaged amemory card being employed, a mechanical door which prevents access tothe storage module 110, or a mechanism which physical rejects thestorage module 110. In this embodiment, the user would submit the codestring to the encryption module 128 via the input module 126 which wouldthen accept the code string and instruct the processing module 120 tounlock the hardware interlock 118 and allow user removal of the storagemodule 110. If the code string is not accepted, the storage module 110will not be able to be removed.

In another embodiment, the device 100 will further include a userverification module (UVM) 130. The user verification module 130 willindicate and verify the identity of the user of the device 100. The userverification module 132 may execute a password protection algorithm ormay include an identity capture device, either incorporated into thedevice 100 or coupled externally via a cable. The identity capturedevice may be a biometric device, such as a retinal scanning device,finger print reader, facial recognition reader or another type of useridentity verification input device which will collect information on theuser to be compared to information that has previously been stored inthe device's memory. One such exemplary fingerprint reader is theBioTouch™ fingerprint reader commercially available from IdentixIncorporated of Minnetonka, Minn. It is to be noted that identitydetection devices such as biometric devices are common and are currentlywidely in use. It is to be further noted, that identity verificationdevices that are not yet in use such as DNA detection, etc, would alsobe compatible with device 100. In this embodiment, the identity of theuser may be required in addition to the entering of a code string todecrypt information on the storage module 110. In a further embodiment,the identity of a particular user may be linked to their code stringand, upon verification of the identity of a user, the linked code stringwill be submitted to the encryption module 128. In another embodiment,the identity of the user may be required to unlock the interlock 118.

According to the various techniques described above, any informationinputted to and/or generated by the GPS device 100 will be securelystored in the storage module 110 whether the type of storage is internalor removable. Only users with an appropriate code string will be grantedaccess to the sensitive information stored in the device 100, e.g.,their home address, contact lists, whereabouts of particularindividuals, etc.

In another embodiment, the encrypted information stored in the storagemodule 110 may be transferred to a user's local computer for furtherprocessing as shown in FIG. 3. The user's local computer 202 willinclude a reader 208 for reading information from the storage module110. It is to be appreciated that the reader 208 may take any form toensure compatibility with the type of storage module 110 used, forexample, reader 208 may be a CD reader, DVD reader, memory card reader,etc. or a combination of readers as are commonly found on conventionalcomputers. If the information is stored in internal memory instead ofremovable memory, the transfer will be done by transmission module 112including hardwired and/or wireless connectivity. The hardwireconnection may include but is not limited to hard wire cabling e.g.,parallel or serial cables, USB cable, Firewire (1394 connectivity)cables, and the appropriate port. The wireless connection will operateunder any of the various known wireless protocols including but notlimited to Bluetooth™ interconnectivity, infrared connectivity, radiotransmission connectivity including computer digital signal broadcastingand reception commonly referred to as Wi-Fi or 802.11.X (where x denotesthe type of transmission), or any other type of communication protocolsor systems currently existing or to be developed for wirelesslytransmitting data. The transmission module will compress and encode theencrypted information for transmission using any known wirelesscommunication technology.

The user's local computer 202 may connected to communications network210, e.g., the Internet, by any known means, for example, a hardwired orwireless connection 203. It is to be appreciated that the network 210may be a local area network (LAN), wide area network (WAN), the Internetor any known network that couples a plurality of computers to enablevarious modes of communication via network messages. Alternatively, theuser's local computer 402 may connect to the network 210 via an InternetService Provider (ISP) 212, where once connected, the ISP server 212will manage the flow of data to other users of the network 210 and/ormanage the flow of information from various web sites connected to thenetwork 210, e.g., content providers residing on servers 214. Thecomputing devices shown in FIG. 3 may communicate to the network 210 viaany known communication link 203, for example, dial-up, hardwired,cable, DSL, satellite, cellular, PCS, wireless transmission (e.g.,802.11a/b/g), etc. Furthermore, the devices will communicate using thevarious known protocols such as Transmission Control Protocol/InternetProtocol (TCP/IP), File Transfer Protocol (FTP), Hypertext TransferProtocol (HTTP), etc. and secure protocols such as Internet ProtocolSecurity Protocol (IPSec), Point-to-Point Tunneling Protocol (PPTP),Secure Sockets Layer (SSL) Protocol, etc.

The user will receive a small code (decryption) program (CEP) from themanufacturer of the device 100 when the user purchases the GPS device100. The CEP program may be distributed on optical media, or othercomputer media, or may also be downloaded from a website on a server 214that the manufacturer provides to the user. Such encryption/decryptionprograms are standard in the industry and include such programs as PGP(Pretty Good Privacy). The user would load the CEP program into hislocal computer 202. The user would then insert the storage module 110from the GPS device 100 into the reader 208 of their computer, oralternatively, transfer the contents of the storage module 110 via thetransmission module 112. The user would provide the computer 202 withthe code string that the user used with the GPS device 100. Thisinformation would then be transferred to a processor of the computer 202that will execute the CEP program which would then verify the codestring as correct and, if correct, allow the processor of the user'scomputer 202 to decrypt the information from the storage module. Oncethe information is decrypted, the user may view the information on adisplay of the computer 202 or print out a hard copy of the informationon a printer 206 coupled to the computer 202.

In the case of routing information, and in a preferred embodiment, theGPS manufacturer may also tie in a mapping program that the user maystore in memory 204 of the local computer 202 or may access via theserver 214. The mapping program would take the route or addressinformation and overlay it on a geographic map to show, for instance,the exact route that the vehicle took or the exact location of thestored address points for a certain time period.

It is to be appreciated that when the CEP decrypts the information fromthe storage module, it does so in the local memory of the user'scomputer 202 or in storage memory of the computer 202 and not on thestorage module. Thus, the information stays encrypted on the storagemodule 110. Of course, if desired, the user could erase any of theinformation on the storage module 110 by using the local computer'sreader 208 to write to the storage module and erase the information.

When the user is finished viewing the information from the storagemodule 110, the user would insert the storage module 110 (stillencrypted) back into the GPS device 100 so that the device 100 is againready to use.

A device, system and method for controlling and storing locationinformation have been described. By encrypting information stored on aGPS device, a user can be confident that their sensitive informationsuch as their home address, personal contacts and addresses, etc. cannot be accessed by other users of the device or by a unknown user in thecase where the GPS device is lost. By encrypting the information on aremovable storage module, a user can check the traveled routes orvelocity of a vehicle containing the device on a local computer withoutthe user of the vehicle tampering with the information. This may beparticularly useful for a parent verifying the destinations visited by achild or for an employer verifying the whereabouts of their employee(s).
